Xarray: confused by reference to dataset in docs for xarray.DataArray.copy

[klindsay28]

The documentation for xarray.DataArray.copy

If deep=True, a deep copy is made of the data array. Otherwise, a shallow copy is made, so each variable in the new array’s dataset is also a variable in this array’s dataset.

I do not understand what dataset is being referred to here. In particular, there are no xarray datasets in the examples provided in this documentation. Could someone provide clarification?

Thanks @klindsay28

We should delete "'s dataset" from that line. The deep kwarg controls whether you get a deep or shallow copy of the variables in the data array (i.e. both coordinate variables and the data variable).

How about

If deep=True, a deep copy is made of the data array. Otherwise, a shallow copy is made, and the returned data array's values are a new view of this data array's values.
